[Dipping process]
Liquid dipping process
Dipping process is a plastic coating process. According to the raw materials of dipping, it can be divided into two types: powder dipping and liquid dipping. It is characterized by a strong and rigid combination of powder coatings.
Most of the liquid dipping process uses hot dipping plastic solution. The thermoplastic coating film has the characteristics of softening when exposed to heat, and can solidify into a film after cooling. It is mainly a physical melt plasticization process, and processing and production are relatively simple. At present, the commonly used code in Zui Code is a synthetic raw material of polyvinyl chloride (PVC) impregnated with polyvinyl chloride (PVC) and additives.
The liquid-impregnated coating is relatively thick and soft, and can be removed from the mold and used as a product with protective properties.
[Dipping process]
It is a new process similar to spray plastic, but thicker and more durable than spray plastic. Ordinary spraying can reach a thickness of a few tenths of a millimeter, while dipping at least a few tenths of a millimeter, it has certain advantages in thickness, which can make the operator use the tools after dipping more useful. And strong.
Good anti-friction ability.
If it is a liquid dipping solution, a series of uses such as different soft hardness, acid and alkali resistance, and corrosion resistance can be prepared according to needs.
[Dipping process]
Dipping thickness is greater than spraying. Those with a thickness of a few millimeters or more are dipped. The impregnated product is based on steel and the weather-resistant polymer resin is the outer layer (thickness 0.5-1.0MM). It has the characteristics of corrosion resistance, rust resistance, acid and alkali resistance, moisture resistance, insulation, aging resistance, good feel, environmental protection and long life , Is a replacement product of traditional paint, galvanized coating film, and has a wide range of uses.
Treatment methods for plastic impregnation defects of plastic impregnation equipment: Lack of plastic-plastic impregnation equipment increases processing injection temperature; increases injection pressure; improves material fluidity. Split seam and overflow—lower the injection temperature; increase the clamping force; reduce the injection pressure; reduce the fluidity from the formula point of view. The surface is matte and not bright-increase the injection processing temperature; dry the material to reduce the moisture of the raw material. Poor viscosity-fully dry the material before injection processing; increase the injection temperature; adjust the formula. Deformation of injection molding of products——enhanced mold cooling of dipping equipment; proper extension of clamping time. Product sticky mold-add release agent or lubricant.
